what did Warren Magnuson do wrong to lose?

and not only lose but by a non-trivial margin of eight points? He was not overly liberal, considerably less liberal than Murray and had been in office for six decades. People with that much seniority rarely lose unless they are scandal plagued (like Ted Stevens). I think it might have had to do with the west coast voters not showing up after Carter conceded which explains why Reagan won the state by 13 points.
